Product Details

Place of Origin	Guangdong, China		Brand Name	PHOTON
Model Number	PTT2103

Product Description

1310nm Optical Transmitter

PTT2103 is a high performance forward path transmitter.19 inches rack mount structure, high linearity and low noise 1310mm DFB laser and state of the RF control circuits, pre-distortion, these make PTT2103 a desirable choice for metro HFC network.

PTT2103 uses 1310nm DFB laser with high linearity and low noise. Pre-distortion circuit improves the performance and stability of DFB laser. AGC/ATC mechanism provides protection to laser and ensures the performance and stability module and feedback to intelligent system platform. This ensures the laser to work at normal status and high performance.

Features

1310 optical transmitter
Selectable AGC (automatic gain control) or MGC (manual gain control)
Accepts low signal input levels
Front panel LCD display
Low RIN, High CNR
High CSO, CTB and XMOD
High linearity and low noise DFB laser, large transportation capacity.
Effective Automatic Temperature Control (ATC) and Automatic Power Control (APC) of the laser to ensure stable operation.
Microprocessor control and monitor
RS-485 interface for remote monitoring and control
45~870 MHz bandwidth
RF pre-distortion circuit for excellent CNR and low distortion performance.
